Canker
CLASSIFICATION
ABOUT
Cankers are areas of dead tissue infected by bacterial or fungal disease, caused by a variety of pathogens. They are most common on plants weakened by environmental stresses, such as drought. Cankers vary in size and shape and usually appear on bark as localized, sunken lesions.
How to treat?
- Biological
If possible remove and destroy the infected parts of the plant. Burn it or toss it into the garbage. Do not compost.
For bigger cankers removal seek an arborist specialist.
- Disease prevention
Avoid mechanical damage to plants.
Prevent plant stress by optimal watering, fertilizing and protection from sun and frost.
Avoid pruning the tree when the bark is wet.
Use resistant species and cultivars as well as healthy, certified seeds and seedlings.
